Clay Aiken and Ruben Studdard... Together Again!

The two former rivals have been friends for seven years and are excited to be doing this concert tour together. "I couldn't ask for a better tour mate. To be able to share the stage with him again is so exciting," said Aiken in a statement. "He is such a talented artist. He inspires me daily and I think that respect and admiration will truly be reflected in our show."

Studdard, who made a guest performance on "Idol's" results show Wednesday, added, "It is truly a blessing and an honor to be on the stage with my friend. The relationship that we have built over these past eight years will definitely translate into a great show for our fans. And I'm really looking forward to singing the timeless classics every night."

The two will play dates on the East Coast and the Midwest, kicking off the tour on July 23 in Asheville, NC and winding up Aug. 14 in Biloxi, MS. For a complete list of dates, visit Billboard.com.
